FARE-CALCULATOR.

Specification of Letters Patent.

ppliation mea January 2e, 1911. seriai No. 604,895.

To all whom it may concern:

Be it known that I, HARRY P.v C. BnowNE,

vothers skilled in t-he art to which it appertains to make and use the same.

'My present invention relates to improve-l ments in calculating devices for calculating or checking the fares to be charged. for va rying distances traversed by a vehicle of any character.V

The invention is more especially applicablejjto use in calculating or checking the fares charged by taxicabs, and it is especially intended to provide a simple mechanical device by which the. passenger. may either calculate in advance the'cost of a proposed trip, or may have a check on the charge made by the driver at the end of any given trip.

The invention is especially adapted to cities laid out in rectangular blocks, but where irregularities exist in the general direction of the streets, lines may be drawn in on the map of the city crossing each other at-right angles, in continuation of or parallel to the streets inthe more regular portions of the city.

--In the accompanying dra-wings, I have selected the city of New York as one having wide variations in the general arrangement of the streets in the lower portion of the city, and having the streets laid out intersecting at right angles in the upper portion of the city, thus showing the wide latitude with which the device may be used.

Referring to the accompanying drawings-Figure 1 represents a plan view of the device, and Fig. 2 represents a central vertical section through the device.

The device consists essentially of'three concentric disks B, C, and D, mounted upon aV suitable block A, The disk B is stationary, and the disks C and D are adapted to berotated about the pivot E. b, e, and (Z represent the outer edges of the three disks. The upper disk D shows afmap of the city, or of a portion of the city inclosed in the circle d', and outside of this circle on the disk are graduations corresponding to the streets running in one direction, say north and south. For convenience of reference, these graduations are put on opposite sides of the disk, those on one side for estimating when traveling to the eastward, or east of the meridian, and those on the opposite side/ ofjthe disk when traveling westward, or west ofthe meridian. This is preferable, so that the reading hereinafter to be explained may always be in the same or additive direction, but obviously a single series of graduat-ions might be used reading additively when going to the eastward, and subtractively when going to the Westward, or' vice versa, as will be hereinafter more fully described. j

The disk. C projects beyond the disk D, exposing a ring which i's graduated to correspond to the streets intersectinggthose indicated by the graduations on the inner disk D, which in New York, for instance, includes all of the numbered streets uptown, and they cross -town or imaginary streets downtown. Where the direction' of the streets is irregular, as in the lower'portion ofthe city, imaginary streets A, B,.C, D, E, F, G, H, I, and J are drawn at equidistant intervals, corresponding to say tive blocks of the uptown district, and in a similar way the north and south streets (or avenues) are continued inthe irregularly laid out district, and numbered l, 2, 3, 4, to 16, respectively. The imaginary street marked 1 .is a continuation of Avenue D, 2' is a continuation of Avenue C, 3 is a continuation of Avenue B, 4 a continuation of Avenue A, 5 a continuation of First avenue, 6 is a continuation of Secondavenue, 7 -is a continuation of Third avenue, 8 a continuation'of Lexington avenue, 8a a continuation of Park avenue, 9 a continuation of Madison avenue,

. 10 a continuation of Fifth avenue, 11 a continuation of Sixth avenue, etc. The imaginary avenues and the avenues that they are continuations of are shown on both sides of\ the disk D. On the projecting annular portion of the disk C, the imaginary cross streets J, I, H,'.G, F,'E, D, C, B, and A are shown, corresponding to the cross lines drawn through the irregularly laid out portion of the city, the imaginary cross street B corresponding to 5th street extended, and the imaginary cross street A corresponding to 10th street extended, above which upto 200th. street, the city is laid out in rectangular blocks, andA the cross-town streets are spaced equal distances apart, there being sol approximately twenty uptown blocks to the mile. Assuming that the fare is charged by miles and quarter miles, the outer and fixed circle is graduated at 50c, the initial and` lowest charge corresponding to the first half mile of travel, and ten cents additional for each additional quarter of a mile, the scale -of charges running from 50e to $5, "as

` angle drawn from the pivot E; the distances being expressed on D and C in fractions of miles, and on B by fractions of dollars. The

layout of New York is such that best results are secured by allowing one mile distance,

or the charge therefor, to subtend an angle of 30. So that scale -D is laid off by scaling from the city map the number of feetl separating avenue from avenue, and calculating from them the angular separation of the avenues on the scale. For example if the distance from 3rd ave. to 2nd avenue,

scales 660 feet, or 2; mile, the angular separation of the avenues in question is 35"-0, orV 3 45 f Now to operate the device, suppose the passenger, or prospective passenger, wishes to go north from the Battery, at the southwest corner ofthe city, to 140th street, and west to 11th avenue. The Batteryis located at the intersection of the arbitraryAvenue 8 and the arbitrary cross-town street J. Now move the letter J on the street circle tot the Zero mark to the right of the $5 mark on the tariff circle; then follow the tarili' circle in the direction of the hands of a clock to 140th street, and it will be noted that the charge would be $3.80, but the Battery is located on the arbitrary line 8,7corresponding to Lexington avenue'uptown, and you wish to go to 11th avenue, which is a continuation of the arbitrary line .16. Now, maintaining the intermediate or street circle in ,this position, turn the inner or avenue circle until the numeral 8 thereon points to the numeral 140 on the street circle, corresponding to 140th street, and then reading around to the right, in the additive direction, you will find that 11th avenue, corresponding to the imaginary avenue marked 16, points between $4.30 and $4.40. Then the-charge for the trip from the Battery to 140th street would be $4.40, the charges for taxicab services in New Yorlrbeing always the next high ligsite 125th street, and you willisee that this charge would be $2.70.., Now to go from Third avenue to First avenue, take4 the east going scale on the inner circle and place Third avenue, corresponding to theA numeral 7, opposite 125th street, and read to the right or in the additive direction. Youwill find that the charge is something over $2.80, or $2.90 net. I

It will be noted that the inner disk has two scales, one for going West,and the other for going east. A single scale could be used to read backward going east, but this would require alittle more intelligence, and it is preferable to. have the scales on opposite sides of the 'disk reading in reverse directions, so that the readings may always be had additively. For convenience in distinguishing the real from the imaginary streets or avenues, it would be preferable to have the real streets'and avenues and the imaginary streets and avenues in different colors.

. It will be. noted that where a city is laid out regularly, there will be no necessity for the imaginary streets and avenues, and also that it will not be necessary to show a map of more than a small portion of such a city. This would be particularly the case with Philadelphia, Where the city is laid out in regular rectangles.-

Thisherein described arrangement happens to be particularly convenient for Manhattan Island, in the greater portion of which the blocks are laid out in regular rectangles ofl substantially equal size, and where most of the streets are numbered consecutively, but in a city where the streets are notnumbered the map could be divided up into a series of.

grid lines, and every fifth or every tenth street marked in bold type, whereby the necessity for calculating as to each, individual street might be avoided. By this arbitrary arrangement, as is shown in Fig.

. 1, representing the lower portion of the city of New'York, any ditliculty in computing fares due to irregularities in the distances be- "i tween the streets will be provided against, as in some partsof the city the blocks are short, and in -others long; and by, arranging the arbitrary lines equal distances apart,

a substantially accurate apportionment and calculation may be made.

It will be obviously more convenient to in number. For instance, if there are more streets running east and west than there are north and south, the larger scale would Vmark on the small circle those avenues or streets which are Acomparatively the fewest dicate fares for the distance traversed, sub-l -between the roadways running in one t1on, graduations on the other disk corregive greater room for graduations, and therefore the smaller circle could more conveniently be used to indicate the lesser number of streets or avenues. With this exception, it is immaterial on which one of the three concentric circles the streets, the avenues, or the ilares are indicated. In other words, the fare circle might be put in b'e.- tween the street and avenue circles, and the position of the street and avenue circles might also be reversed, if desired, without varying the capacity of the instrument.

It will be obvious that the lower xed disk I3 may be cut away inits center, leaving only a ring exterior to the disk C, and said disk C may be inclosed in and iush with said ring. While I have shown the instrument as apiplied for use in the city of New York, it will be obvious that it might be applied toany city in which the general lformation of the blocks is rectangular.

The instrument is not only adapted for use by prospective and actual passengers for estimating or checking the fares imposed by taximeters or similar Alievices, but is adapted to form a substitute for taximeters in many cases, such as those in which the vehicle is owned by the driver or where the privacy of the service is incompatible withl the .display of a taximeter. For such purposes its value lies in .the fact that thedistance charged for is the shortest distance between the termini of the trip. It affords a quick method of estimating the cost of a trip in any vehicle whose 4charges, are fixed bylaw, and also 'affords a ready means for checking any material error the reading of the ter .installed on the vehicle, or any attempted extortion on the part of the driver.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is 1. An apparatus comprisin a fixed, circular scale and two rotatab e, concentric,

graduated disks, the upper disk being provided with means for indicating the region to be traversed including intersecting lines representing roadways, graduations on said upper disk corresponding to the distiirlices sponding to the distances between the roadways crossing the first mentioned roadways, and graduations on said circular scale to` instantially as described. 2. apparatus comprisin three vsuperposed, concentric, graduated disks, one fixed and the other two rotatable, the upper disk being rotatable and provided with means for indicating the region to be traversed including intersecting lines representing roadways, graduations on said upper disk corresponding to the distances between the roadare regisways running in one direction, graduations onfanother of said disks corresponding to the" distances between the roadways crossing the first mentioned' roadways, and a disk graduated to indicate fares for the distance traversed, substantially as described.
